SPECIFICATION forming part of Letters Patent No. 350,511, dated October`12, 1886.

Application filed March 24, 1886. Serial No. 196,408. (Model.)

To all whom t may concern:

Beit known that I. JOSEPH E. TOFT, a citizen ofthe United States,residing at Exira. in the county of Audubon and State of Iowa, haveinvented a new and useful Combined Sash- Holder and Safety-Lock, ofwhich the fol1owing is a specification.

My invention consists of a combined sashholder and safety lock; and theobjects of my invention are, first, to provide facilities for thebalancing and locking of upper and lower sashes of windows in anydesired position independently of each other; second. to obviate thewear and indentation ofwindow sash and casings; third,to providefacilities for ease and convenience in the manipulation of sashes. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective view of jambras ing ofwindow-frame after removal of sash, showing the position of sash-holderas applied to window-frame. Fig. 2 is a vertical section ofjambcasing,showing operation'of shaft A, cam C, and metallic plate D.

Similarletters refer to similar parts through out the several views.

The shaft A, crank B, 4cam C, metallic plate D, and spring F constitutethe working parts of the invention. Crank lB turns shaft A, forcing camC against metallic plate D, which comes in contact with window-sash,holding same at any desired position. Spring F, compressed by downwardpressure of crank B, returns to position over upper side of crank B andholds same in position until release, as shown in Fig. l. The cam C onshaft A is adjustable, and can be applied to upper or lower sash.` ShaftA passes through inside window casing and jamb, as shown in Figs. l and2and is kept in place by esontcheon, that portion of vshaft passingthrough i escutcheou being reduced in size. Cam C Works on shaft A in anaperture cut in the sash-slide of Window-frame,vas\ shown in Fig. v2.Plate D is a flexible metallic plate covering the aperture in which camC works, the upper part of plate D being slightly curved and sunk. intojambcasing` to which it is secured at upper end by wood-screw. l

I am aware that prior to .my invention there have been patented andconstructedvarious apparatuses for balancing and locking windowsash. Itherefore do not claim such a combination, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,.is-

In a sash holder and lock, the combination of the crank B and escutcheonE with the shaft A. cam C, adjustable on shaft A, metallicfriction-plate D, and springcatch F, all` as substantially set forth anddescribed.
